Specification of Letters Patent.

Application filed November 12, 1920. Serial No. 423,578.

7 '0 (ZZZ to 710m it may concern Be it known that I, CLARENCE G. \Vmo- L'EY, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in a Rain-l/Vater Cut-Oil, described and claimed in the following specification.

This invention relates to automatic valves for rain spouts and more particularly to an apparatus to be installed in arain spout leading from the root' of a building whereby the water will be directed into a sewer tor a short time after the water begins to drain from the root whereupon the valve will automatically operate to direct the water into a cistern or supply tank.

Other objects of the invention will appear upon consideration otthe following detail description and accompanying drawings,- wherein Figure 1 is a longitudinal section through the apparatus constructed in accordance with my invention showing the parts in position to direct the water into the sewer.

Figure 2 is a similar view showing the mechanism in reversed position whereby the water may be directed into the cistern.

leiierring to the drawing by numerals, the pipe 1 is connected to the rain spout in any preferred manner and the valve body 2 is enlarged to permit the mechanism to be mounted therein. The lower portion of the valve body 2 is provided with two outlets 3 and 4:, the outlet 3 leading to a sewer and the outlet 4 leading to a cistern, as clearly indicated in the drawings. A central transverse shatt 5 mounted in the valve body is provided with a gear 6 which meshes with segmental gear 7 mounted on another shaft 8. A deflector plate 9 is fixed to the segmentary gear 7 so that it will swing with the gear 7 whereby its angular position may be char ged. Fixed to the shaft 5 is a collar 10 to which is secured a tubular member 11, hollow throughout its length and oi arcuate formation as shown in the drawing. The tubular member 11 is secured to the collar 10 intermediate the ends of the member so that oppositely extending portions of the pipe or tubular member 11 provide hollow supporting arms 12 and 18. A receptacle or bucket 14 is provided at its top with a screen cover 15 of conical formation, the top being secured to the bucket 141 and also swingingly supported by the arm 13 in a manner that will establish communication between the interior of the bucket and the interior of the tubular member 12 so that water flowing through the tubular member may be deposited in the bucket 14%. A stop member 16 is carried by the end of the arm 13 for engagement with the defiecting'plate 9 when the parts are in the position shown in "Fig. 1 of the drawing. The opposite end of the tubular member, or the arm 12 is provided with a weight 17 which has a portion of its interior hollowed out to provide'a receptacle 18 within the weight. The weight 17 however, is suflicient to normally overbalance the weight of the receptacle 14 at the opposite end of the tubular member. Each end of the deflecting plate is provided with perforations'lt) and 20 and the bottom of the bucket 14 is also provided with fine perforations 21.

WVhen the device is installed in a rain spout the pipe 1 will be connected to the spout leading from the roof of the building, the outlet pipe 3 will be connected to a pipe leading to the sewer, and the outlet pipe 4. will be connected to a pipe leading to a cistern or other suitable tank for receiving the clean rain water. The parts are normally in the position shown in Fig. 1 of the drawings. During the commencement of the rain falls, the water draining off the roof of the building will be dirty and it will pass down through the pipe 1 and engage the deflecting plate 9 so that the water will pass downwardly over the edge of the deflecting plate and out through the outlet 3 into the sewer.

A portion of this water, however, will pass through the perforations 20 in the edge of the plate, through the screen cover 15 ot the bucket and then into the bucket. This will cause the bucket 14 to be slowly filled su'fiiciently to overbalance the weight 17 at the opposite end of the tubular member 11. hen this occurs, the tubular member will swing to the position shown in Fig. 2 ot the drawing thus rotating the gear 6 which, by virtue of its engagement with the segmental gear 7 will turn the latter and swing the deflecting plate to the posit-ion shown in Fig. 2 of the drawing. In this manner the water will be deflected through the outlet opening 4 and into a supply tank or cistern. The per forations 19 in the opposite end of the defleeting plate will permit a portion of the water to flow into the hollow 18 in the weight 17 and this water will flow through the tubular member 11 to keep the bucket 14 filled in spite of the tendency of the bucket to drain through the perforations 21. During the rain storm, therefore, the water will all be deflected into the cistern. After the rain storm when the water ceases to flow,

the contents of the bucket 14: will slowly V spirit of the invention or the scope of the claims hereunto appended. What I claim is H 1. An automatic valve for rain spouts comprising a valve body having an inlet opening, and two outlet openings, a deflecting plate swingingly mounted in the valve body beneath the inlet opening, a tubular arm swingingly mounted in the body beneath the said deflecting plate, a bucket at one end of the arm, ahollow weighted member at the opposite end of the arm andnormally overbalancing the said bucket, gearing mecha nism connecting the said hollow arm with the said deflecting member to cause a swinging movement of the deflecting member when the hollow armis swung in either direction, the end portions of the deflecting plate being perforated whereby aquantity of the water passing over the deflecting plate may be received in the hollow weighted member, the said tubular member establishing conununication between the said weighted member and the bucket.

' 2. An automatic valve for rain spouts comprising a valve body, a deflecting plate swingingly mounted within the body and provided with perforations at each end, a shaft to support the said plate, a segmental gear on the said shaft, a second shaft below the deflector shaft equipped with a gear in mesh with the segmental gear, a hollow supporting arm secured to the lower shaft, a bucket having perforations in its bottom and provided'with a screen top connected to one end of the said hollow supporting arm, a hollow weighted member secured to the 0pposite end of the hollow supporting arm, and normally overbalancing the weight of the said bucket but adapted to be swung to an elevated position when the bucket is filled with water through perforations in one end of the deflector plate.

3. An automatic valve for rain spouts comprising a valve. body, a deflecting plate swingingly mounted within the body and provided with perforations at each end, a shaft to support the said plate, a segmental gear on the said shaft, a second shaft below the deflector shaft equipped with a gear in mesh with the segmental gear, a hollow sup porting arm secured to the lower shaft, a bucket having perforations in its bottom and provided with a screen top connected to one end of the said hollow supporting arm, a hollow weighted member secured to the opposite end of the hollow supporting arm, and normally overbalancing the weight of the said bucket but adapted to be swung to an elevated position when the bucket is filled with water through perforations in one end of the deflector plate, the said hollow supporting arm being arcuate whereby water may flow from the said hollow weighted member into the bucket when the said weighted member is in its uppermost position and in engagement with the said deflector plate.

In testimony whereof, I have alfixed my signature in the presence of two witnesses.
